CUT-OUT.

SPECIFICATION forming part of Letters Patent No. 600,593, dated March 15, 1898.

Application filed October 7, 1897.

To all whom it may concern.-

Be it known that I, AUGUSTUS R. MoNnILL, a citizen of the United States, residing at Oldfields, in the county of Hardy and State of West Virginia, have invented certain new and useful Improvements in Cut-Outs, of which the following is a specification.

My present invention relates to improvements in cut-outs for telephone and telegraph circuits, and is fully illustrated in the accompanying drawings, in which Figures 1 and 2 are perspective views of the device, showing the parts in a different relation; Fig. 3, a side elevation of the device, showing the means employed for making and breaking the circuit; and Fig. 4, a detail view of one ofthe connections.

The object of my invention is to provide means whereby any single instrument may be out out at the pleasure of the owner thereof and the main line closed, so that the circuit may not be broken or interrupted.

The invention is designed particularly for use in connection with telephone-circuits such as are used in country stations and where it is often desirable to cut out a particular instrument when a local storm is in progress.

In the drawings, A denotes a post carrying at its upper end a cross-bar 13, upon which bar are mounted two insulators C and D. The incoming branch of the main circuit (indicated by the letter E) is connected to the insulator O and terminates in a contact-piece F. The outgoing branch of the main circuit (denoted by the letter G) is connected to the insulator D and terminates in a contact-piece II.- A second cross-bar I is secured upon the post at right angles to the cross-bar B and carries at its ends pivoted arms J and K. Each of the arms J and K is provided with a counterweight L, which normally tends to hold said bar in an upright or vertical position. At the inner end of each of the arms J and K, I provide a cross-bar M, to which are attached suitable contact-pieces N, N, N and N Contact-pieces N and N" are directly connected by a wire 0. The contact-pieces N and N carried upon the opposite member K, are connected with the incoming and outgoin g wires P and Q, which are in circuit with the instrument placed within the house.

To bring one or the other of thearms J or Serial No. 654,448. (No model.)

K down into a horizontal position and there by bringing the contacts into connection, I employ a device such as shown in detail in Fig. 3. To the inner end of each of the bars J and K there is connected a cord or rope R, which passes over pulleys S, T, and U, the pulleys U being placed at a point convenient to a window or door, so that the handles V, connected to the ropes or cords R by a spring WV, may be conveniently reached. The cords, as will be seen, pass down through a plate X, which limits the upward move ment of the spring, while a plate Y, provided with notched projections, is secured below said plate X at such a point that when the handle V is engaged with one of the notches it will pull down one of the arms J or K, as the case may be, and hold the same in such position that the circuit is completed through its contacts. The spring WV will serve to keep the contacts in close relation with each other, and no matter whether the cord be a metallic one or one liable to elongation or shrinkage from moisture the contacts will always be kept in such close relation that the circuit will not be interrupted.

With the parts in the relation shown in Fig. 1 the local instrument is cut out and the main line completed through the contacts F and N, line 0, and contacts N and II to the outgoing branch G of the main line. With the parts in the relation shown in Fig. 2 the instrument is in circuit with the main linethat is, the current passes in from the line E, through contacts F and N through branch P, through the instrument, out through the branch Q, through contacts N and H, and on to the main line G.

Upon reference to Fig. 4 it will be seen that the lower contacts carried by the cross-bar B are of a frusto-conical form, while the upper contact-pieces carried by the cross-bars are hollow and designed to fit down over the lower contacts, effectually preventing any foreign substance from entering in between the two surfaces and thus impairing the continuity of the circuit.

While I have shown this form of contact and have found the same to be successful in practical use, I do not desire to limit myself to this exact form, nor do I wish to be understood as limiting myself to the precise arrangement of the cords or cables R used for drawing down one or the other of the bars or arms J and K.

Having thus described my invention, What I claim is- 1. In a cut-out, the combination of an interrupted main line; a support; a single pair of contacts for the terminals of the main line carried by said support; a short line carried by an arm and normally out of contact with the main line; a local line carried by a second arm, also normally out of circuit With the main line; and means for moving either arm and bringing either of the lines into circuit with the main-line terminals.

2. In a cut-out, the combination of an interrupted main line; a support; a single pair of contacts for the terminals of the main line carried by said support; two arms pivoted to the support and normally held out of opera tive relation with the main-line contacts; a short line carried by one of the arms; a local circuit connected to the other; and means for bringing either arm down and establishing connections with the main-line terminals through the short line or through the local circuit.

8. In a cutout, the combination of an interrupted main line; a support; a single pair of contacts for the terminals of the main line carried by said support; two arms pivoted to the support and normally held out of operative relation with the main-line contacts; a short line carried by one of said arms; a local circuit connected to the other arm; and cords connected to the arms and extending down from the support for drawing one or the other of the arms into contact with the terminals of the main line.

4. In a cut-out, the combination of an interrupted main line; a support; a single pair of contacts for the main-line terminals carried by said support; two arms pivoted to the support and normally held out of operative relation with the main-line contacts; a short line carried by one of the arms; a local circuit connected to the other arm; cords connected to the arms and extending down from the support for drawing one or the other of the arms into contact with the terminals of the main line; and springs connected to the ends of the cords, substantially as and for the purpose described.

5. In a cut-out, the combination of an interrupted main line; a support; contacts for the terminals of the main line carried by the support; weighted arms J and K, pivoted to the support; contacts N, N and circuit 0 carried by arm J contacts N and N carried by arm K, and a local circuit connected with said contacts; cords connected to the inner ends of the arms extending down the support to a convenient point for manipulation by the operator; and springs connected to the ends of the cords, substantially as described.

6. In a cut-out, the combination of an interrupted main line; a support 13; contacts F, H, connected to the terminals of the main line; cross-bar I; counterweighted arms J, K, pivoted to said crossbar; arms M carried at the ends of the arms J, K; contacts N N and circuit 0; contacts N and N connected with a local circuit; cords R connected to the inner ends of arms J and K and extending down the support to a point convenient for manipulation by the operator; and springs connected to the ends of the cords.

In witness whereof I hereunto set my hand in the presence of two witnesses.
